昨日、カーネルをアップデートするためにapt-get upgradeを実行しました（ubuntu 15.04）が、/bootのメモリが不足しました（通常、十分なスペースがないと、アップグレードタスクの実行が妨げられます）
誤ってアクティブカーネルを削除してしまったため、次の手順に従うことになりました -誤ってすべてのカーネルを削除した後、システムを復元するにはどうすればよいですか?
以前のメモリ エラーにより、現在のカーネルのインストールや残りのカーネルのアップグレードが妨げられているため、手順 13 で停止しています。
アップグレードで次のエラーが発生します

これは上記の質問に直接関連するものではなく、dpkgの問題であるため、独自の質問が必要であると考えています。
答え1
他に何をすればいいのかわからなかったので、パッケージを削除しました
sudo apt-get remove linux-image-extra-3.19.0-31-generic
そして再インストールした
apt-get -y upgrade linux-image-generic
効果があったようだ
